Abstract
The utility model relates to a marine air pipe head which is used for preventing liquid from flowing into a vent pipe. The utility model is composed of a hollow pipe base which is provided with an air channel, semi-enclosed side covers at both sides of the pipe base and a float positioned in the pipe base. The utility model is characterized in that the float is a metal hollow ball with a thin wall, and a seal ring on a blow vent in the pipe base is provided with a circular arc face which matches with a ball float. The utility model adopts the structure to realize the automatic sealing of the blow vent, the sealing effect can not be influenced by external conditions and seasons, and the structure is simple.
Description
The utility model relates to a kind of breather pipe, particularly a kind ofly is used to prevent that liquid from flowing into the marine air pipe head in the vent line.
Widely used fuel bowl air pipe head mainly is the hollow base by the band air by-pass passage on the boats and ships.Be positioned at base floating drum or floating cake, the pilot bar that links to each other with floating drum or floating cake, be convenient to base top cover that floating drum or floating cake are mentioned and fixed, and the semi-enclosed side cover in base both sides is formed.The deficiency of this floating drum or floating cake formula air pipe head is: the vent on floating drum or floating cake and the base inwall is a plane contact, and when hull tilts, floating drum or floating cake will depart from vent, not have sealing process; Automatically closed vent mouth, and need manual operation to realize, use trouble, when meeting stormy waves, manually the work of closing is difficult to finish; At severe winter, pilot bar freezes easily, it can't be mentioned the closed vent mouth.
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of simple in structure, good sealing effect is provided, and can realize osed top float-ball type air pipe head automatically.
The purpose of this utility model is achieved in that the float-ball type air pipe head is by the hollow base that has air by-pass passage, the semi-enclosed side cover of base both sides, and the float that is positioned at base, its special character is that described float is a ball float, it is the thin-wall metal hollow ball, preferably adopts antiseptic property stainless steel metal ball preferably.Because ball float is swivel, so its whichever face all can contact with vent, also can not tilt depart from vent because of hull.
Seal ring in the base on the vent has the arc surface that matches with ball float, improves its sealing effectiveness.
The utility model compared with prior art has following characteristics: utilize ball float to come the closed vent mouth, no matter how hull tilts, all can not influence sealing effectiveness.Can realize automatic closed vent mouth, it is convenient especially to use, and is not subjected to external conditions and seasonal effect.Simple in structure.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the left view of Fig. 1.
Be described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1 and Figure 2, the base (1) that has air by-pass passage (2) is for having the double-layer hollow cylinder of base, and its base and cylinder end face are perpendicular.The cylinder both ends of the surface are provided with filter screen (3), with prevent foreign material enter base hollow in, the filter screen outside is provided with semi-enclosed side cover (4), is fixed on the base end face with bolt (5).Vent in the base is provided with the seal ring (6) of band arc surface, and it is to adopt liquid glue directly to be compressed on the vent, utilizes ball float to roll on its contact surface then and makes, and assurance seal ring and ball float match.Ball float (7) is the stainless steel metal hollow ball, and it is hollow that it is positioned at base, and its course of processing is: at first stainless steel sheet is stretched and make hemisphere, utilize argon arc welding that two hemispheres are integrally welded then, polish polishing at last.
Air pipe head is in opening state usually, and with the airiness in the maintenance cabin, when liquid flows in the base by semi-enclosed side cover, ball float will float with liquid, with the vent sealing, prevents in liquid inflow or the infiltration cabin.
Claims (3)
1, a kind of float-ball type air pipe head, it is by the semi-enclosed side cover of the hollow base that has air by-pass passage, base both sides, and the float composition that is positioned at base, it is characterized in that described float is a ball float.
2, float-ball type air pipe head according to claim 1 is characterized in that the seal ring on the vent has the arc surface that matches with ball float in the base.
3, float-ball type air pipe head according to claim 1 is characterized in that ball float is the thin-wall metal hollow ball.
